Summary of the invention
Goal of the invention: the purpose of this utility model is in order to overcome deficiency of the prior art, provides a kind of and handles the turbidity height, treatment effect is good and connection and reasonable arrangement, floor space is little, one-time investment is low, long service life, water purifier that level of automation is high.
Technical scheme: high turbidity turriform water purifier described in the utility model, it comprises flocculation reaction district, the tube settling district that is arranged on equipment tower body top, be arranged on the mud enrichment region at equipment tower body middle part, be arranged on the sand filtrating area of equipment tower body bottom, be arranged on the back flushing district of equipment tower body one side, in described tube settling district, lay inclined tube, adjustable automatic sludge discharger is set, between described tube settling district and sand filtrating area, be provided with header in described mud enrichment region inside.
Be provided with water inlet pipe on described equipment tower body top, be provided with rising pipe at described equipment tower body middle part.
One side is provided with water leg in described flocculation reaction district.
Former water is finished hydrolysis flocculation, processes such as absorption through dosing and coagulant aids thorough mixing.Current are that flow lifting type flows into the flocculation reaction district from bottom to top, further strengthen the degree of flocculation reaction, can make the impurity particle in the water, and colloid is collided contact betwixt fully, absorption.After flocculation reaction, the sedimentation gradually of flocculation mud, but still the tiny mud of some particle enters the settling region because of proportion is less with current.Design polypropylene hexagon cellular inclined tube filler in the settling region can improve the laminar flow regime of current, and particles settling do not disturb by current, obtains sufficient sedimentation in limited space, makes the particulate matter of water separate removal with colloid.The body refuse enrichment region of structure uniqueness is set and mixes adjustable automatic mud removing, unnecessary body refuse is in time got rid of, thereby guaranteed that the sedimentation body refuse can not cause secondary pollution, improved the reliability that particulate matter and colloid are removed in the water.Former water flow to filtrating area by water gathering system after inclined tube clarification, disperseed to enter the muddy water district by baffle plate, the bed of material after filtration from the muddy water district again, and supporting layer enters the catchment area.Suspended substance in the water, colloid is trapped once more, and water has obtained purification again, is qualified thereby assurance enters the water of catchment area.Filter back clear water enters clear water zone, clear water before filter with filter back two liquid level potential difference effects under or under the former effect of water pressure, enter clear water zone from the catchment area from bottom to top along the clear water pipe, again from the discharger that flows automatically after clear water zone overflows into the water leg at top.
Equipment is after operation for some time, filtration chamber's inner suspension thing concentrates on the filtering layer surface, filtering layer both sides pressure reduction increases, filter chamber hydraulic pressure is increased, when the quick filter tank of filtrate district water level rises to certain altitude, promptly begin to form automatic back-washing, make the interior filtrate of autogenous pressure recoil filter chamber of water, reach the backwash effect.When descending certain water level in the settling pond, make siphon destructive, back flushing stops, and the filter tank enters the operation of next cycle and filters.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: the equipment integral layout is simplicity generosity more, more attractive in appearancely rationally saves investment, big, the wear-resisting wiping of filtrate intensity, easily flushing, long service life.
Embodiment
As shown in Figure 1, high turbidity turriform water purifier, comprise the flocculation reaction district 2, the tube settling district 3 that are arranged on equipment tower body 1 top, be arranged on the mud enrichment region 4 at equipment tower body 1 middle part, be arranged on the sand filtrating area 5 of equipment tower body 1 bottom, be arranged on the back flushing district 6 of equipment tower body 1 one sides, in described tube settling district 3, lay inclined tube 7, in described mud enrichment region 4 inside adjustable automatic sludge discharger 8 is set, between described tube settling district 3 and sand filtrating area 5, is provided with header 9; Be provided with water inlet pipe 10 on described equipment tower body 1 top, be provided with rising pipe 11 at described equipment tower body 1 middle part; 2 one sides are provided with water leg 12 in described flocculation reaction district.The utility model equipment integral layout simplicity generosity, attractive in appearance rationally saving is invested, big, the wear-resisting wiping of filtrate intensity, easy flushing, long service life.
